Mikronite

[Marine One]

The way I understand it is the more carbon you add, the stronger the steel. Low carbon steel gives us stamped steel fenders and panels. Medium carbon steel gives us blocks, cranks, rods and gears. High carbon steel gives us springs and fuel injection parts.

What cryo treating does for us is it transforms brittle austenite into a much tougher material called martensite. A downside to this is the fact that we could end up with what I guess I will call "unstructured martensite" for lack of a better term.

To help illustrate my point, an extreme example would be like pulling all the carbon out of a high carbon steel spring with five coils and putting it back in at the first, second and third bottom coils. By definition it is still a coil spring made with high carbon steel, but the way the carbon is structured makes the top portion of the spring vulnerable.
